Intensive pre-operative information course (IPIC) and pre-operative weight loss results in long-term sustained weight loss following bariatric surgery: 11 years results from a tertiary referral centre.

INTRODUCTION: Outcomes of long-term (5-10-year) weight loss have not been investigated thoroughly and the role of pre-operative weight loss on long-term weight loss, among other factors, are unknown. Our regional bariatric service introduced a 12 week intensive pre-operative information course (IPIC) to optimise pre-operative weight loss and provide education prior to bariatric surgery. The present study determines the effect of pre-operative weight loss and an intense pre-operative information course (IPIC), on long-term weight outcomes and sustained weight loss post-bariatric surgery. METHODS: Data were collected prospectively from a bariatric center (2008-2022). Excess weight loss (EWL) ≥ 50% and ≥ 70% were considered outcome measures. Survival analysis and logistic regression identified variables associated with overall and sustained EWL ≥ 50% and ≥ 70%. RESULTS: Three hundred thirty-nine patients (median age, 49 years; median follow-up, 7 years [0.5-11 years]; median EWL%, 49.6%.) were evaluated, including 158 gastric sleeve and 161 gastric bypass. During follow-up 273 patients (80.5%) and 196 patients (53.1%) achieved EWL ≥ 50% and ≥ 70%, respectively. In multivariate survival analyses, pre-operative weight loss through IPIC, both < 10.5% and > 10.5% EWL, were positively associated with EWL ≥ 50% (HR 2.23, p < 0.001) and EWL ≥ 70% (HR 3.24, p < 0.001), respectively. After a median of 6.5 years after achieving EWL50% or EWL70%, 56.8% (154/271) had sustained EWL50% and 50.6% (85/168) sustained EWL70%. Higher pre-operative weight loss through IPIC increased the likelihood of sustained EWL ≥ 50% (OR, 2.36; p = 0.013) and EWL ≥ 70% (OR, 2.03; p = 0.011) at the end of follow-up. CONCLUSIONS: IPIC and higher pre-operative weight loss improve weight loss post-bariatric surgery and reduce the likelihood of weight regain during long-term follow-up.

Peritoneal Flap Hernioplasty for Reconstruction of Large Ventral Hernias: Long-Term Outcome in 251 Patients.

BACKGROUND: Repair of large ventral hernias is challenging when primary fascial closure cannot be achieved. The peritoneal flap hernioplasty, a modification of the Rives-Stoppa retromuscular mesh repair, addresses this problem by using the hernial sac to bridge the fascial gap and isolate the mesh from both the intraperitoneal contents and the subcutaneous space. It is applicable to both midline and transverse hernias. We report the results from our institution using this repair based on a retrospective review of 251 cases. METHODS: Patients undergoing peritoneal flap hernioplasty repair from January 1, 2010-December 31, 2014 were identified from the Lothian Surgical Audit system, a prospectively maintained computer database of all surgical procedures in the Edinburgh region of southeast Scotland. Patient demographics, clinical presentation, location of the hernia and surgical treatment were obtained from the hospital case-notes. Follow-up consisted of a clinical consultation 3 months postoperatively and a retrospective review of patient files completed December 2018. Patients presenting signs of complications were assessed during a clinical review. RESULTS: Two hundred and fifty-one patients underwent incisional hernia repair, 68.1% in the midline and 31.9% arising through transverse incisions. Forty-three of these (17%) were recurrences referred from other centers. Mean BMI was 32.1 kg/m2 (range 20-59.4 kg/m2). Mean defect width was 9.2 ± 4.2 cm (range 2.5-24.2 cm). Mean mesh size was 752 cm2 (range 150-1760 cm2). Some form of abdominoplasty was performed in 59% of cases. Mean postoperative stay was 6.3 days (range 1-33 days). Mean follow-up time was 75 months (range 44-104 months). Fifty-three patients (21.1%) developed postoperative complications. Three (1.2%) developed superficial skin necrosis and 27 (10.8%) a superficial wound infection, but none developed deep mesh infection. Twelve (4.8%) developed symptomatic seroma and 11 (4.4%) a hematoma requiring surgical intervention. Seven (2.8%) patients developed recurrence within the follow-up period. CONCLUSION: Peritoneal flap hernioplasty is an excellent and versatile method for reconstruction of large ventral hernias arising in both midline and transverse incisions. The technique is safe and associated with few complications and a very low recurrence rate.

A prospective study of gastro-oesophageal reflux disease symptoms and quality of life 1-year post-laparoscopic sleeve gastrectomy.

INTRODUCTION: There are concerns that laparoscopic sleeve gastrectomy (LSG) can cause severe gastro-oesophageal reflux disease (GORD). The aim of this study was to assess GORD symptoms and quality of life following LSG. METHODS: A prospective study of patients undergoing LSG (2014-2016) was performed with follow-up by DeMeester Reflux/Regurgitation Score, Bariatric Quality of Life Index (BQLI) and Bariatric Analysis and Reporting Outcome System (BAROS) Score pre-operatively, 6 months and 1-year post-operatively. RESULTS: Twenty-two patients were studied. Mean modified DeMeester Reflux/Regurgitation Score improved from 2.25 (±0.67) pre-operatively to 0.81 (±0.25) at 12 months (P = 0.04). At 12 months, two patients had symptomatic reflux, but overall satisfaction score was unaffected. Mean BQLI Score underwent a non-significant improvement at 12 months. BAROS Score showed all patients to have excellent (n = 19) or very good (n = 3) results (12 months). CONCLUSION: GORD symptoms improve for most patients' 1-year post-operatively. A small proportion of patients will develop troublesome GORD, but overall satisfaction remains high.

Laparoscopic partially extraperitoneal (PEP) mesh repair for laterally placed ventral and incisional hernias.

Laparoscopic mesh repair is becoming an increasingly popular method of ventral and incisional hernia repair. Entrapment neuropathy is a recognised complication when tacks are used to fix the mesh, particularly below the inguinal ligament and laterally in the abdominal wall. We describe a novel method of ventral hernia repair, which employs transabdominal extra-peritoneal dissection to create a pocket for mesh placement with complete avoidance of tacks in the postero-lateral abdominal wall. This technique is particularly useful for incisional hernias arising through old stoma wounds or appendicectomy incisions, and for Spigelian and lumbar hernias.

Second opinions in remote surgical practice using email and digital photography.

BACKGROUND: Email offers the opportunity to improve communication between surgeons across the world. This experimental study aimed to assess the feasibility of obtaining clinical opinions by email and digital photography in remote surgical practice. METHODS: Over a 3-week period, all adult general surgical cases with a visual component to their condition admitted to a remote developing-world hospital were invited to participate. Clinical details and digital images were emailed to a UK general surgeon who consulted specialist colleagues if required and emailed back a suggested diagnosis and management plan, rating the confidence with which these were made on a five-point scale. The concordance between diagnoses and management plans from each centre were rated by three independent general surgeons. RESULTS: In this prospective study of 32 patients, 56% of diagnoses and 78% of management plans were made by the UK surgeons with 'high' or 'total' confidence. Causes of low diagnostic confidence included vague swellings and low-resolution X-ray images. Diagnostic and management concordance between centres was adjudged 'high' or 'total' in 88 and 43% of cases, respectively. CONCLUSION: Obtaining second opinions using email and digital photography is feasible in adult general surgery, but its efficacy is limited in cases where image resolution or non-visual clues are important.

Surgical service centralisation in Australia versus choice and quality of life for rural patients.

High patient volume for both hospitals and surgeons is an important determinant of operative mortality and outcome for complex and infrequently performed operations. The 13% of Australia's population who live in rural and remote areas often choose to have surgery close to home and support networks despite the potentially higher operative mortality and morbidity. Rural patients should be able to make an informed choice about having their surgery locally. Rural and metropolitan surgeons should discuss and reach mutual agreement on where each patient is best treated. A balance must be struck between quality of services that can be provided locally and geographic convenience.

Prospective comparison of routine and selective operative cholangiography.

BACKGROUND: In a rural centre with limited resources and no endoscopic retrograde cholangiopancreatography facilities, a prospective cohort study was established to compare policies of routine and selective intraoperative cholangiography (IOC) in order to develop a local protocol. METHODS: Patients undergoing laparoscopic cholecystectomy from 1 February 1995 to 30 November 2002 were allocated to undergo routine or selective IOC according to birth date. Those with known common bile duct (CBD) stones were excluded. Selective IOC was performed on the basis of abnormal liver function tests or a dilated CBD on ultrasound. Study end points after 12 months follow-up were retained CBD stones, CBD injury, operating times and the effect of IOC on the management of patients with persistent biliary symptoms postoperatively. RESULTS: Of the 148 patients in the routine group, 94 underwent IOC and CBD stones were shown in 12. Of the 155 in the selective group, IOC was performed in 34 of 45 eligible patients and stones were shown in five. Sixteen patients re-presented with recurrent biliary symptoms or jaundice postoperatively and eight had proven retained CBD stones, of whom only one had undergone (false-negative) IOC. There was no significant difference in mean operating time (56 vs 61 min; t-test P = 0.15). There was one CBD injury in each group, both incurred after successful IOC. CONCLUSIONS: There was no difference between policies of routine or selective IOC in relation to operating times, retained CBD stone rates or CBD injury. However, the authors found management of patients with recurrent biliary symptoms easier if an IOC had been performed, and IOC was easier to perform when the staff were expecting it. Thus a policy of routine IOC has been adopted.
